Config Reference

Looking for something other than config? The functions and classes are in the API reference; the props each chart accepts are in Chart props and Callbacks and payloads; and what the framework bindings call those props is in Framework props.

A mochart config is a plain object made of per-concern sections. Every section — and almost every property inside one — is optional and falls back to a sensible default, so a minimal config only names the data properties to plot (see Getting started).

This reference is generated from the library source: the same descriptions, validators, and defaults that power config validation produce these pages, so they cannot drift from the code.

The list sections (series, valueAxes, gradients, groups, stacks) take an array of config objects and have a companion *Defaults section for values shared by every entry — see The config model for how sharing and defaulting work.

Property	Description	Default
accessibility	Configure the chart accessibility features and screen-reader labels	{}
animation	Configure the chart animation settings	{}
categoryAxis	Configure the chart category axis content and styling	{}
chart	Configure general settings of the chart	{}
colorPalette	Configure the color palettes to use for collections of series	{}
crosshair	Configure the crosshair styling and behavior when a category and/or series is focused	{}
id	An optional identifier for the config (any value; the chart only compares it — a changed id resets the chart)
legend	Configure the chart legend which itemizes the series	{}
linearGradients linearGradientDefaults	Configure linear gradients to be applied to series Configure common properties for all linear gradients	[]
pie	Configure the pie/donut slice geometry and slice labels (applies when chart.type is pie)	{}
plot	Configure the chart plot content and styling	{}
radialGradients radialGradientDefaults	Configure radial gradients to be applied to series Configure common properties for all radial gradients	[]
series seriesDefaults	Configure the chart series Configure common properties for all series	[]
seriesGroups seriesGroupDefaults	Configure the grouping of series Configure common properties for all series groups	[]
seriesStacks seriesStackDefaults	Configure the stacking of series Configure common properties for all series stacks	[]
title	Configure the chart title	{}
tooltip	Configure the chart tooltip styling and behavior	{}
valueAxes valueAxisDefaults	Configure the chart value axes content and styling Configure common properties for all value axes	[]
version	The version of the configuration format (optional: omitted means the current format; include it in stored or shared configs so future releases can migrate them)
